simple sinatra extension to authenticate users against github oauth

README.md

sinatra_auth_github

A sinatra extension that provides oauth authentication to github. Find out more about enabling your application at github's oauth quickstart.

To test it out on localhost set your callback url to 'http://localhost:9393/auth/github/callback'

The gist of this project is to provide a few things easily:

  • authenticate a user against github's oauth service
  • provide an easy way to make API requests for the authenticated user
  • optionally restrict users to a specific github organization
  • optionally restrict users to a specific github team

Installation

% gem install sinatra_auth_github

Running the Example

% gem install bundler
% bundle install
% GITHUB_CLIENT_ID="<from GH>" GITHUB_CLIENT_SECRET="<from GH>" bundle exec rackup -p9393

There's an example app in spec/app.rb.

Example App Functionality

You can simply authenticate via GitHub by hitting http://localhost:9393

You can check organization membership by hitting http://localhost:9393/orgs/github

You can check team membership by hitting http://localhost:9393/teams/42

All unsuccessful authentication requests get sent to the securocat denied page.

API Access

The extension also provides a simple way to access the GitHub API, by providing an authenticated Octokit::Client for the user.

def repos
  github_user.api.repositories
end

For more information on API access, refer to the octokit documentation.

Extension Options

  • :scopes - The OAuth2 scopes you require, Learn More
  • :secret - The client secret that GitHub provides
  • :client_id - The client id that GitHub provides
  • :failure_app - A Sinatra::Base class that has a route for /unauthenticated, Useful for overriding the securocat default page.
  • :callback_url - The path that GitHub posts back to, defaults to /auth/github/callback.

Enterprise Authentication

Under the hood, the warden-github portion is powered by octokit. If you find yourself wanting to connect to a GitHub Enterprise installation you'll need to export two environmental variables.
